This metadata document describes the data contained in the "processedData" folder of this data package. This data package contains all data collected by the Argos System from 921 satellite transmitters attached to adult Pacific walruses in the Bering and Chukchi Seas, in U.S. and Russian waters, 1988-2019. The raw data were processed to accomplish two goals: flag implausible location estimates and decode raw sensor data. Very few transmitters (n=5) also carried GPS receivers. Because the GPS locations were communicated through the Argos System, a time series of Argos (Doppler) tracking data for those 5 transmitters also exists and is included. Four Comma Separate Value (CSV) tables are included in the "processedData" folder of this data package: 1) the "GPS_filteredLocations" table contains one record for every GPS location obtained, accompanied by a binary flag that denotes an algorithm's plausibility check (based on a speed threshold of 35 m/s); 2) the "diag_filteredLocations" table contains one record for every Argos location estimate collected, accompanied by a binary flag that denotes an algorithm's plausibility check (based on distance, turning angle, and rate thresholds). Each record in both the GPS and Argos filtered-location tables also includes a 'Tracking_Status' variable that denotes whether the location was collected from a live animal, a dead animal, or shed transmitter, 3) the "decodedSensor" table contains decoded sensor data such as the transmitter's temperature, battery voltage, and motion (activity), and 4) the "deploymentAttributes" table contains one record for each transmitter deployment in a CSV formatted table. The deployment attributes file contains information such as when the transmitter was attached to the animal, when tracking of a live animal ended, and a variety of variables describing the animal and transmitter. This table is identical to the "deploymentAttributes" table in the "rawData" folder of this data package.

This data package contains all data collected by the Argos System from 921 satellite transmitters attached to adult Pacific walruses in the Bering and Chukchi Seas, in U.S. and Russian waters, 1988-2019. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) contain the raw Argos DIAG (Diagnostic) data, one in the legacy verbose ASCII format and one in a tabular Comma Separated Value (CSV) format. Two other data files (with identical content) contain the raw Argos DS (Dispose) data, one in the legacy verbose ASCII format and one in a tabular CSV format. The fifth file, "deploymentAttributes", contains one record for each transmitter deployment in a CSV formatted table. The deployment attributes file contains information such as when the transmitter was attached to the animal, when tracking of a live animal ended, and a variety of variables describing the animal and transmitter. This table is identical to the "deploymentAttributes" table in the "processedData" folder of this data package.

This data release includes 2 child items with tracking data for Pacific walrus, a marine mammal that ranges between the Alaska Peninsula, up through the Bering and Chukchi seas, and over to Russia. Child Item 1: "Argos Satellite Tracking Data for Pacific Walrus (Odobenus rosmarus divergens) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Pacific Walrus (Odobenus rosmarus divergens) - Raw Data" -- All raw data collected from Argos satellite transmitters, provided for completeness of the archive. The quality-controlled, "Argos Processed Data" (Child Item 1) are better suited for most analytical purposes.

This metadata document describes the data contained in the "Argos Processed Data" (Child Item 1) of this data release. This data release contains all data collected by the Argos System from 32 satellite transmitters attached to Whimbrels on their breeding range in arctic and western Alaska, 2006-2010. The raw data were processed to accomplish two goals: flag implausible location estimates and decode raw sensor data. Three Comma Separate Value (CSV) tables are included in the "Argos Processed Data" (Child Item 1) of this data release: 1) the "diag_filteredLocations" table contains one record for every Argos location estimate collected, accompanied by a binary flag that denotes an algorithm's plausibility check (based on distance, turning angle, and rate thresholds). Each record also includes a 'Tracking_Status' variable that denotes whether the location was collected from a live animal, a dead animal, or shed transmitter, 2) the "decodedSensor" table contains decoded sensor data such as the transmitter's temperature, battery voltage, and motion (activity), and 3) the "deploymentAttributes" table contains one record for each transmitter deployment in a CSV formatted table.

This data release includes two summary geospatial rasters in GeoTIFF format indicating the seasonal Pacific walrus distribution apparent from location tracking obtained from the temporary attachment of Argos transmitter tags to 325 adult Pacific walruses (248 female, 67 male, 10 unknown) between 1987 and 2015. We deployed tags on walruses at locations in the eastern and northern Bering Sea, the eastern Chukchi Sea, and southern coast of the western Chukchi Sea. We estimated daily locations and characterized seasonal distributions (May-November and December-April) across the Pacific Arctic on a coarse grid (50km resolution).
